27. The answer is A. Staphylococcus.
Explaination:
The Bacillus, Clostridium and Sporosarcina are the examples of endospore producing bacteria whereas staphylococcus is not endospore producing bacteria.
28. The answer is C. Fimbrae.
Explaination:
The short, fine, hairlike bristles that aid in adhesion in prokaryotic organisms are called fimbrae.
29. The statement is True.
Explaination:
Archaea do not have peptidoglycan membrane. It is present in the almost all bacterial cells which are gram positive and gram negative.
30. The answer is D. Cell wall.
Explaination:
Gram positive bacteria cell wall contain thick layer of peptidoglycan with techoic acid whereas gram negative cell wall contains thin layer of peptidoglycan.
31. The answer is false.
Explaination:
Iodine is not used as a decolorizer. It is used as Aa mordent in gram staining.
